SULKY DIRT-SCRAPER.

SPECIFIGATION forming part of Letters Patent No. 277,826, dated May 15,1883.

Application' filed September 27, 1881. (No'modeld To all whom it mayooncern y Be it known that I, HIRAM M. DLL. BAB- COX,ofModesto, countyof Stanislaus, State of California, have-invented an Improved SnlkyDirt-Scraper; and I hereby declare the following to be a full, clear,and exact description thereof.

M yinvention relates to a dirt-scraper, which, by reason of beingadapted to run on two wheels, I call a sulky dirt-scraper. i

It consists in a frame, to the aXle ofV which is secnred adownwardly-projecting board or plank, under the lower edge of which aninclined blade or cutter is adapted to be pnshed forward or withdrawn bythe action of a supplementary frame pivoted above, and swinging studs,all of which will hereinafter more fully appear, reference being` madeto the aceompanying drawings.

Figure 1 is a perspective view of my scraper. Fig. 2 is a longitudinalvertical section of the same.

Let A represent the draft-pole, extending` behind the axle B, to whichit is attached. O O are the wheels, and D the honnds or braces attachedto the pole andaxle.

To the axle B, in front thereof, I attach the plate, plank, or board E.This extends downwardly at a slightly backward inelination nearly to theground-in ordinary practice, for example, to within six inches thereof.It extends across the front of the axle nearly the whole width. To thetop of the pole, a little forward of the aXle, is hinged or pivoted asupplementaryframe,F. (Here shown triangular in shape, thongh this neednot be so of necessity.)

` This frame is so hinged as to be adapted to be raised from the rearabout its hing'ed apex as a center. Across the rear end of the frame Fis a brace or shaft, G. The pole A does not extend quite to this shaft,and is provided on its rear end with a platform, H. The frame F has acentral piece, I ,which extends rearward nearly to the platform and liesupon the pole, its end being between two standards, J J, which areattached on each side of the pole. In the upper part of these standardsare spring-catches (o a, which allow the piece I to pass up and Spring,`out when it has passed, so as to prevent it from falling down. It th nslocks the frame F when its rear end is raised. Any device or means forreleasing the spring-catches a ar, so as to drop the frame, may beemployed.

To the rear ends of the frame F, on the under side, are Secured stripsor piecesKK, which extend forward and are downwardly iuclined. Theirends extend under thelower edge of the them a cutter or blade,.L, whichis suspe'nded between the lower edge of the plank E and theV ground. Theknife containing the downward iucliuation of the strips K, to which itis attached, is also iuclined downwardly, and the lower edge of theplank E is preferably beveled in a like direction. The strips K K arefurther secured t'o the frame F by the side braces, M, attached to theframe above. Upon the brace or shaft G, about it-s middle, is journaleda sleeve, N, io which are secured the studs O O. These are preferablymade of gaspipe, and are long enough to raise the frame F snificiently,as hereinafter explained. P is a lever attached to the sleeves N, by theoperation of which the studs O O may be swung around the brace G- overfrom the rear to the front.

Q represents the driver7s seat. It is seeured to the pole A by anyconnection or standard which will allow it to be moved farther forwardor back thereon. I have here shown a slot in the end of the support anda bolt.

The Operation of this device is as fbllows: lt is intended to be drawnby horses attached to the pole A. The frame F lies horizontahin whichposition the cutter or blade L extends under the plank E, and is readyto be embedded in the earth. The studs O O extend out behind and dragalong` the gronnd. A man stands on the platform H, his weight being,`balanced by the driver, on the forward portion of the pole. Theoperator, by stepping npon the brace G, forces theirear end of the frameF down, and causes the blade or cutter L to press into the earth. Whenthe machine is advanced the dirt is carried forward by the plank orcarrier E, and when the point is reached where it is desired to drop andscrape it, the operator, by moving the lever P, throws the studs O Oover forward with their ends on the ground. The machine, advancing`still, canses the frame F to rise by reason of the studs assnming theperpendicular. The frame F, in' rising, withvplank or board E, and theyhave Secured to i draws its blade L from under the carrier, and the dirtis spread by the carrier between its lower edge and the ground. Theframe F, when raised, is locked in the standards, and remains untilreleased, when the same operation is repeated. The dirt may be thuscarried, dnmped, and spread at intervals and places desired.

By having the driveris seat adjustable I can balance the Weight withbetter effect in front of and behind the axle, and thus am enabled touse two wheels.

Having thus described myinvention, what I claim as new, and desire tosecure'by Letters Patent, is-

1. In a sulky-scraper, the front board or'carrier, E, in combinationwith the hinged or `jointed frame F, having braces G and K K, and ablade or' cutter, L, and the swingiug studs O O, snbstantially as andfor the purpose zo herein described.

2. In a sulky-scraper having a polc, A, a-xle B, and wheels O, the frontboard or carrier, E, in combination with the hinged or jointed frame F,having a central piece, I, adapted to be Secured in the standards J, andprovided with braces G K K, and a cutter or blade, L, and the swingingstnds O O, substantially as herein described.

3. The combination and arrangement, in a sulky scraper, of theadjustable seat Q, the pole A, and the platform H, substantially as andforthe purpose herein described.

In witness whereof I hereunto set my hand.
